Bently Nevada 177230-01-01-05 Seismic Transmitter for Vibration Monitoring

Product Introduction

When machinery vibration threatens uptime and safety, the Bently Nevada 177230-01-01-05 Seismic Transmitter delivers precise, real-time measurements you can trust. This compact transmitter converts vibration velocity into a standard 4-20 mA current loop signal, making it ideal for integration with PLCs, DCS, and SCADA systems. Built with a hermetically sealed 316L stainless steel case, it withstands harsh industrial conditions while providing accurate RMS vibration data from 10 Hz to 1 kHz.

Technical Specifications Breakdown

The 177230-01-01-05 offers a measurement range of 0 to 25.4 mm/s (0 to 1.0 in/s) with ±10% accuracy. Its frequency response spans 10 Hz to 1 kHz (600 to 60 kcpm) ±10%, ensuring reliable detection of common machinery faults. The output signal is a 4-20 mA current loop, where 4 ± 0.3 mA equals 0.0 mm/s and 20 ± 2 mA equals full scale range. Excitation voltage is 12 to 30 Vdc, current limited to 40 mA. The transmitter operates from -40°C to +85°C and tolerates up to 100% relative humidity (non-submerged).

Industry Applications

In rotating machinery such as pumps, fans, compressors, and turbines, the 177230-01-01-05 provides continuous vibration monitoring to detect imbalance, misalignment, or bearing wear. Its rugged design suits oil and gas, power generation, and chemical processing plants where reliability is paramount. The multiple approvals (CSA/NRTL/C, ATEX/IECEx) allow deployment in hazardous areas without additional enclosures.

Installation & Setup Guidance

Mount the transmitter using the 1/4-28 UNF or M6 x 1 SI / M8 x 1.25 SI threads, applying 4 to 7 N-m (35.4 to 62.0 in-lbf) of torque. Connect the 3-pin MIL-C-5015 connector per the wiring convention: Pin A for 4-20 mA positive loop, Pin B for loop return, and Pin C for dynamic acceleration signal. Allow less than 15 seconds settling time within 2% of final value after power-up. Ensure the power supply is current-limited between 30 mA and 35 mA for optimal performance.

Maintenance & Reliability

With a hermetically sealed sensor and 316L stainless steel construction, the 177230-01-01-05 requires minimal maintenance. Its mounted resonant frequency exceeds 12 kHz, and transverse sensitivity is less than 5% of sensitivity, reducing false readings. Periodic inspection of the connector and mounting integrity is recommended. The transmitter's 100% non-submerged humidity rating and shock survivability of 9.810 m/s² (1.000 g peak) ensure long service life in demanding environments.

Buying Guide & Selection Advice

When selecting the 177230-01-01-05, verify that your measurement range and frequency response requirements match the 0-25.4 mm/s and 10 Hz to 1 kHz specifications. Confirm that your system accepts a 4-20 mA input and provides 12-30 Vdc excitation. For hazardous area installations, ensure the approvals (CSA/NRTL/C, ATEX/IECEx) meet local regulations.
